Abstract. Despite the copious researches carried out during the last decades in many parts of the world, the seismic response of masonry infills is still an important aspect to investigate, both from numerical and experimental point of view. Indeed, due to the numerous aspects that may differ depending by the local building practise and the period of construction of the infill, and the interactions with the structure, widespread in-plane damages and out-of-plane collapses of masonry infills are still often observed during the last post-seismic inspections. The experimental studies conducted to improve the understanding of the in-plane and out-of-plane seismic response of masonry infills have aimed at different goals that have led to implement specific testing protocols. Within the European FP7 INSYSME Project, the research unit of the University of Pavia has conceived a new seismic resistant masonry infill system able to control the in-plane damage in the masonry, reduce the interactions with the structure and guarantee the out-of-plane stability. Specific testing procedures have been therefore developed for in-plane cyclic and out-of-plane dynamic tests on shaking table on one-storey one-bay infilled RC frames. In this paper, these original testing procedures applied to the innovative infill and the background necessary to implement them are presented, along with the testing setups and some of the most significant results.
Keywords: experimental tests, masonry infills, in-plane cyclic tests, out-of-plane tests, shaking table tests.
